Metadata Editor

The Complete Guide to ID3 Tags & Metadata

The Adiminium Metadata Editor allows you to modify the hidden information stored inside your MP3 files. This data, known as ID3 Tags, is what music players (like Spotify, iTunes, or your car stereo) display when a song is playing. Without metadata, your file is just "Unknown Artist - Track 01". With metadata, it becomes a professional release.

Key Fields Explained

• Title: The actual name of the song (e.g., "Bohemian Rhapsody").
• Artist: The performer or band (e.g., "Queen").
• Album: The collection the song belongs to (e.g., "A Night at the Opera").
• Year: The release year. Critical for sorting music chronologically.
• Genre: Helps streaming algorithms and players categorize your mood (e.g., "Rock", "Pop", "Podcast").

Why Metadata Matters

1. Professionalism: Sending a demo to a record label? If the file says "audio_final_v3.mp3" with no artist name, it might get lost. Tagged files show you care.
2. Organization: Music libraries rely 100% on tags to sort your collection. Untagged files end up in the "Unknown" void.
3. Copyright/Credit: While not a legal lock, having your name in the Artist/Composer tag is the first step in asserting ownership of your work.

How It Works

This tool uses the browser-id3-writer library to inject binary data frames into the header of your MP3 file.
MP3 files are structured as a series of frames. The ID3 tag usually lives at the very beginning (ID3v2) or the very end (ID3v1) of the file. We rewrite these headers without re-encoding the audio stream, meaning zero loss of audio quality.

Step-by-Step Guide

1. Upload: Select an MP3 file. (Note: Only MP3 is supported for ID3 tagging).
2. Edit: The tool reads existing tags. Change the text in the input fields.
3. Save: Click "Save & Download". A new MP3 file is generated with your updated tags embedded.
